- Example embodiments will now be described more fully with reference to the accompanying drawings.
- With initial reference to
FIG. 1 , an ignition assembly according to the present teachings is generally illustrated atreference numeral 10. Theignition assembly 10 generally includes acoil body 12, anignition boot 14 removably mounted to thecoil body 12, and aspark plug 16. Theignition assembly 10 can be any suitable ignition assembly for nearly any internal combustion engine, such as a motor vehicle engine for example. - The
coil body 12 generally includes acase 18, anelectrical connector 20, and afastener 22. Theconnector 20 extends from the case and is configured to connect with any suitable current source. Thefastener 22 extends through thecase 18 to secure theignition assembly 10 at any desired location. For example, thefastener 22 can secure theignition assembly 10 to, or proximate to, an internal combustion engine. - The
ignition boot 14 generally includes aplug hole seal 24, apole joint 26, and acap plug 28. Theplug hole seal 24 is removably connected to thecase 18 of thecoil body 12. Thepole joint 26 is coupled to theplug hole seal 24, and thecap plug 28 is connected to thepole joint 26. Theplug hole seal 24, thepole joint 26, and thecap plug 28 are aligned along a longitudinal axis A of theignition boot 14. Thespark plug 16 is received within thecap plug 28. - With continued reference to
FIG. 1 and additional reference toFIG. 2 , additional features of theignition assembly 10 will now be described. With respect to thecase 18 of thecoil body 12, thecase 18 includes abushing 30 extending therethrough, which receives thefastener 22. Thecase 18 further includes ahigh voltage tower 32 extending from thecase 18. Thehigh voltage tower 32 is generally annular. Protruding outward from thehigh voltage tower 32 is aretention tab 34. Theretention tab 34 can be an annular tab that extends continuously around thehigh voltage tower 32, or theretention tab 34 can include a plurality oftabs 34 spaced apart from one another. Theretention tab 34 releasably cooperates with theseal 24 to removably couple theseal 24 to thecase 18. - A
retention clip 36A is mounted to thecoil body 12 within thehigh voltage tower 32, and aresistor 38 is releasably coupled to theretention clip 36A. Theretention clip 36A retains theresistor 38 in cooperation with thecoil body 12 when theboot 14 is separated from thecoil body 12. Therefore, theboot 14 can be separated from thecoil body 12 for replacement or repair without theresistor 38 becoming disconnected from thecoil body 12 and, for example, falling to the ground. Theretention clip 36A is electrically coupled to theconnector 20 in any suitable manner, such as with one or more conductors (not shown). Additional details theretention clip 36A are set forth herein, such as in conjunction with the description ofFIGS. 4A-6B . - The
seal 24 defines areceptacle 40. Thereceptacle 40 is sized and shaped to receive aflange 42 extending from afirst end 44 of the pole joint 26. Theflange 42 can be retained within thereceptacle 40 in any suitable manner, such as with an adhesive or mechanical connection, to connect the pole joint 26 to theseal 24. Extending from asecond end 46 of the pole joint 26 is anadditional flange 48. Theflange 48 and areceptacle 50 of thecap plug 28 are sized and shaped to cooperate with one another to secure the pole joint 26 to thecap plug 28. Theflange 48 can be retained within thereceptacle 50 in any suitable manner, such as with a suitable adhesive or mechanical connection. - The
boot 14 defines abore 52 that extends through theboot 14 along the longitudinal axis A. Thebore 52 includes aninner surface 54 that extends completely through each of theseal 24, the pole joint 26, and thecap plug 28. At theseal 24, thebore 52 receives therein thehigh voltage tower 32 and theretention clip 36A with theresistor 38 mounted thereto. Thebore 52 provides a passageway through theboot 14 from thehigh voltage tower 32 to anorifice 56 of thecap plug 28 at adistal end 58 of theboot 14. - Secured within the
bore 52 is anignition coil 60. Theignition coil 60 includes afirst diameter portion 62 and asecond diameter portion 64. Thefirst diameter portion 62 has a greater diameter than thesecond diameter portion 64. Thesecond diameter portion 64 is provided on both sides of thefirst diameter portion 62. Thefirst diameter portion 62 has a diameter that is slightly larger than an inner diameter of thebore 52 at the pole joint 26. Therefore, friction between thefirst diameter portion 62 and theinner surface 54 of thebore 52 retains theignition coil 60 within theboot 14. Theignition coil 60 is arranged within theboot 14 such that it is in electrical contact with theresistor 38 at one end and in electrical contact with thespark plug 16 at an opposite end. - The
spark plug 16 generally includes a terminal 66,ribs 68,external threads 70, acentral electrode 72, and alateral electrode 74. Thespark plug 16 extends through theorifice 56 and into thebore 52. Thespark plug 16 is arranged such that the terminal 66 and theribs 68 are seated within thebore 52 and theexternal threads 70 are connected to, for example, a cylinder head of a motor vehicle engine. Theignition coil 60 is in electrical contact with the terminal 66 to conduct current between theresistor 38 and the terminal 66. - With additional reference to
FIG. 3 , thecoil body 12 is illustrated without theboot 14 connected thereto. Theretention clip 36A retains theresistor 38 within thehigh voltage tower 32 even when theboot 14 is removed. Without theretention clip 36A, upon removal of theboot 14 there would be nothing to retain theresistor 38 within thehigh voltage tower 32, and thus theresistor 38 would be free to fall out from within thehigh voltage tower 32. - With reference to
FIGS. 4A and 4B , additional details of theretention clip 36A will be described. Theretention clip 36A generally includes abase 80,legs 82, and fingers 84. Thebase 80 includes afirst surface 86 and asecond surface 88 that is opposite to thefirst surface 86. The base 80 can be made of any suitable electrically conductive material, such as copper or any other suitable metal. - The
legs 82 extend fromfirst surface 86 of thebase 80. Twolegs 82 are illustrated, but theretention clip 36A can include any suitable number oflegs 82. Thelegs 82 are illustrated as extending generally perpendicular to thebase 80, but may be arranged in any other suitable manner as well. Thelegs 82 are secured within thecoil body 12 and are in electrical contact with components of thecoil body 12. - At a center of the
second surface 88 of thebase 80 is abase conductor 90. Thebase conductor 90 extends from thebase 80 and is illustrated as having a pointedtip 92. Thebase conductor 90 conducts current between theretention clip 36A and theresistor 38 coupled thereto. Thebase conductor 90 can thus have any suitable shape or size to conduct current between theretention clip 36A and theresistor 38. - The fingers 84 extend from the
second surface 88 of thebase 80. As illustrated, theretention clip 36A includes fourfingers 84A-84D (FIG. 4B ) spaced evenly apart about the base at 90° intervals. Each finger 84 includes adistal end 94 that is opposite to thebase 80. Proximate to thedistal end 94 of eachfinger 84A-84D is a taperedportion 96. Each of the taperedportions 96 extend, or taper, inward toward a longitudinal axis B of theretention clip 36A. - Although the
retention clip 36A includes fourfingers 84A-84D, any suitable number of fingers 84 can be provided, and the fingers 84 can be spaced apart at any suitable interval. For example and with reference to FIGS. 5A and 5B, aretention clip 36B is illustrated including threefingers FIGS. 6A and 6B atreference numeral 36C. Theretention clip 36C includes twofingers retention clip 36A, and thus the similar features are designated with the same reference numbers. - With additional reference to
FIGS. 7A-7C , coupling of theretention clip 36A with theresistor 38 is illustrated. Theresistor 38 generally includes afirst conductor 102 and asecond conductor 104 at opposite ends thereof. Between thefirst conductor 102 and thesecond conductor 104 is abody portion 106, which has an outer diameter that is smaller than outer diameters of each of the first and thesecond conductors resistor 38 is coupled to theretention clip 36A by aligning theresistor 38 along the longitudinal axis B and pushing thefirst conductor 102 beyond the taperedportions 96 toward thebase 80. As thefirst conductor 102 contacts the taperedportions 96 of thefingers 84A-84D, thefingers 84A-84D expand outward from the longitudinal axis A to allow thefirst conductor 102 to pass beyond the taperedportions 96 and be moved toward thebase 80. Theresistor 38 is pushed along the longitudinal axis A until thefirst conductor 102 contacts the pointedtip 92 of thebase conductor 90. After thefirst conductor 102 passes beyond the taperedportions 96, thefingers 84A-84D are biased to move back toward the longitudinal axis B to their original position and contact, or closely abut, thebody portion 106. With particular reference toFIG. 7C , because the outer diameter of thefirst conductor 102 is greater than the distance between thefingers 84A-84D at thetapered portions 96, thefingers 84A-84D prevent thefirst conductor 102 from passing beyond the taperedportions 96, and thus prevent theresistor 38 from becoming decoupled with the retention clip 36, even when theboot 14 is disconnected from thecoil body 12. - The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
